Development Of New Chemical Probes To Delineate The Polyamine Regulation & Molecular Strategies To Unravel Protein Polyamination, Vennela Tulluri
Development Of New Chemical Probes To Delineate The Polyamine Regulation & Molecular Strategies To Unravel Protein Polyamination, Vennela Tulluri
Theses and Dissertations
Polyamines such as putrescine, spermidine, and spermine modulate critical cellular processes, including gene expression and cell proliferation. Cellular polyamine regulation is a complex mechanism controlled by three different proteins: Ornithine decarboxylase (ODC), Antizyme (OAZ), and Antizyme Inhibitor (AZIN). While ODC is directly involved in polyamine biosynthesis, OAZ, and AZIN regulate the ODC activity via protein-protein interactions. The dysregulation of ODC, OAZ, and AZIN leads to elevated polyamines in numerous pathologies, making them attractive targets for controlling polyamine levels. Besides regulating polyamine synthesis, OAZ modulates polyamine transport. However, the precise mechanism remains elusive. In this research, we discuss our approach to …
Flexural Wave Manipulation By Non-Hermitian Planar Elastic Metasurface, Katerina Stojanoska
Flexural Wave Manipulation By Non-Hermitian Planar Elastic Metasurface, Katerina Stojanoska
Theses and Dissertations
It has been demonstrated that metasurfaces with spatially asymmetric inner geometry exhibit unidirectional scattering effects, which can be used to control waves in a directional fashion. In this thesis, a planar Non-Hermitian elastic metasurface exhibiting unidirectional focusing of flexural waves is proposed. Asymmetrically loaded piezoelectric disks and metallic blocks comprise the unit cells. By using a negative capacitance shunting, a tunable material loss is embedded into the system. With suitable engineering of the induced loss profile, resonating building blocks are designed, which are capable of independently accessing unidirectional zero reflection. A planar metasurface is then created so that constructive interference …
Enhanced Throughput Of Aligned Polyacrylonitrile Nanofiber Manufacturing Via High-Speed Centrifugal Spinning, Jason Glen Ippolito
Enhanced Throughput Of Aligned Polyacrylonitrile Nanofiber Manufacturing Via High-Speed Centrifugal Spinning, Jason Glen Ippolito
Theses and Dissertations
Centrifugal spinning is noteworthy due to its high fiber throughput rate compared to other nanofiber manufacturing platforms. It is capable of producing fibers in the nanoscale diameter range from a multitude of polymers, such as polyacrylonitrile (PAN). With a traditional centrifugal spinner, fiber can be rapidly spun and collected on static posts. However, the use of static posts inevitably forms a dense ring of fiber after a short period of time, and this fiber build up can halt the spinning process. In this work, the factors that influence the throughput and scalability of highly aligned centrifugally spun PAN fibers are …
The Intolerance Of Uncertainty: Transdiagnostic Connections Across Schizophrenia And Mood Spectrums, Obsessive Beliefs, And Physical Health, Sharanjit D. Pujji
The Intolerance Of Uncertainty: Transdiagnostic Connections Across Schizophrenia And Mood Spectrums, Obsessive Beliefs, And Physical Health, Sharanjit D. Pujji
Theses and Dissertations
The ways in which we classify mental health symptoms are closely tied to etiological understandings and interventions. While prominent diagnostic systems are categorical in nature, dimensional and transdiagnostic conceptualizations may provide increased precision and specificity that are more representative of “real-world” symptom presentations. The intolerance of uncertainty (IOU), an aversive state formed in reaction to the fear of the unknown, may have transdiagnostic value across mental and physical health. The current study sought to examine dimensionality across traditionally distinct symptoms and the transdiagnostic role of IOU across physical and mental health through the lens of the schizophrenia spectrum with an …

Targeting The Warburg And Q Effect: Novel Strategy To Disrupt Cancer Metabolism, Mahmoud Adel Mohamed
Targeting The Warburg And Q Effect: Novel Strategy To Disrupt Cancer Metabolism, Mahmoud Adel Mohamed
Theses and Dissertations
One of the hallmarks of cancer cells is their altered metabolism, which serves their need to grow and proliferate. Cancer cells exhibit a marked increase in glucose consumption (Warburg effect). In addition, cancer cells also exhibit excessive uptake of glutamine, for biomass synthesis and for energy production through mitochondrial substrate level phosphorylation (glutaminolysis pathway). Glutamine metabolism is enhanced upon inhibition of glycolysis, also interference of glutamic metabolism leads to upregulation of glucose metabolism. So, simultaneous inhibition of glycolysis and glutaminolysis presents promising metabolic intervention strategy. In this study, we investigated high dose Vitamin C mechanism of action through MTT assays …

Detecting Gene-Gene Or Gene Environment Interactions In Association With Complex Disease Outcomes, Taiwo Adetunji Famuyiwa
Theses and Dissertations
Identifying gene–gene and gene–environment interaction is complicated and gainsaying most especially because of high multifactor dimensions involve in the analysis of such combination discrediting the functionality of parametric statistical method like Logistic Regression. [22] developed a multi-factor-dimensionality reduction (MDR) method for detecting and characterizing high-order gene-gene and gene-environment interactions in case-control and discordant-sib-pair studies with relatively small samples, which is inspired by the combinatorial partitioning method of [18]. [16] proposed Generalized MDR (GMDR) framework based on the score of a generalized linear model which allows adjustment of covariates, provides a unified framework for handling both dichotomous and quantitative phenotypes. However, …

Monolithic Multiphysics Simulation Of Hypersonic Aerothermoelasticity Using A Hybridized Discontinuous Galerkin Method, William Paul England
Monolithic Multiphysics Simulation Of Hypersonic Aerothermoelasticity Using A Hybridized Discontinuous Galerkin Method, William Paul England
Theses and Dissertations
This work presents implementation of a hybridized discontinuous Galerkin (DG) method for robust simulation of the hypersonic aerothermoelastic multiphysics system. Simulation of hypersonic vehicles requires accurate resolution of complex multiphysics interactions including the effects of high-speed turbulent flow, extreme heating, and vehicle deformation due to considerable pressure loads and thermal stresses. However, the state-of-the-art procedures for hypersonic aerothermoelasticity are comprised of low-fidelity approaches and partitioned coupling schemes. These approaches preclude robust design and analysis of hypersonic vehicles for a number of reasons. First, low-fidelity approaches limit their application to simple geometries and lack the ability to capture small scale flow …

Natural Amino Acid Derived Iron (Iii) Catalysts For Green Oxidation Chemistry Applications, Karie Sanford
Natural Amino Acid Derived Iron (Iii) Catalysts For Green Oxidation Chemistry Applications, Karie Sanford
Theses and Dissertations
Tetraamido macrocyclic ligand activators are a group of catalysts that have been developed to perform green oxidation chemistries. In this thesis, the traditional synthesis of these catalysts was successfully altered to begin with natural amino acids, rather than the conventionally used synthetic derivatives of amino acids, which has never been shown in previous research. This was confirmed using a variety of characterization techniques including electrospray ionization-mass spectrometry. One of these catalysts was utilized in several dye degradation studies, where it was determined that the catalyst can remove about 98% of methylene blue and indigo carmine pollutants from water within 45 …

Identification And Quantification Of Allelochemicals Associated With Weed Suppression In Sweetpotato, Varsha Varsha
Theses and Dissertations
Mississippi ranks among the leading states in sweetpotato production in the US. However, managing weeds in sweetpotato fields presents a significant challenge, and the limited availability of herbicides labeled for use in sweetpotato makes it even more challenging. The widespread and repeated use of herbicides has led to the development of weed resistance. In addition, herbicides are incompatible with the organic production system. Finding sustainable weed management strategies to provide weed control options for organic cultivation and detain the development of herbicide-resistant weeds under conventional crop production is imperative. The natural chemicals released by the plants, also called allelochemicals, can …
